Pro tips
- PDF, Word and HTML are supported out of the box — no conversion needed.
- Scanned PDFs are automatically OCR'd so you can summarize them too.
- For very long documents, the first ~30,000 characters are analyzed for speed and accuracy.
- Always review the summary before sharing — AI output is a starting point, not a final draft.
Frequently asked questions
Which file types are supported?
PDF, Word (.docx), TXT, Markdown, HTML, CSV, JSON, XML, YAML and most other plain text formats.
Is the Document Summarizer free?
Yes — 100% free, no signup, no daily limits.
Is my document private?
Yes — text is extracted in your browser, and only the text (not the file) is sent for summarization. Nothing is permanently stored.
Does it work with scanned PDFs?
Yes — we fall back to in-browser OCR automatically when a PDF has no embedded text.
Can it summarize documents in other languages?
Yes — it handles most major languages and returns the summary in the same language as the source.
